與pushViewController有問題！幫助

Question

tabBarController = [[UITabBarController alloc] init]; //Create a tab bar 
view1 = [[View1 alloc] init]; //Create the first view 
UINavigationController *navigationController1 = [[UINavigationController alloc] initWithRootViewController:view1]; 
navigationController1.navigationBar.tintColor =[UIColor blackColor]; 
view2 = [[View2 alloc] init]; //create the second view 
UINavigationController *navigationController2 = [[UINavigationController alloc] initWithRootViewController:view2]; 
navigationController2.navigationBar.tintColor =[UIColor blackColor]; 
tabBarController.viewControllers = [NSArray arrayWithObjects:navigationController1, navigationController2,nil]; 
[window addSubview:tabBarController.view]; 
[window makeKeyAndVisible]; 

上面的代碼來自我的appDelegate類（applicationDidFinishLaunching）。 View1和View2是UIViewController。這是我最初設計我的應用程序的方式，這些應用程序有兩個選項卡（view1和view2）。下面的代碼實現View1中發生的事情，當用戶向左或向右滑動時。

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { 
NSLog(@"I am in touches began methods"); 

UITouch *touch = [touches anyObject]; 
gestureStartPoint = [touch locationInView:self.view]; 

} 


- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { 

UITouch *touch = [touches anyObject]; 
CGPoint currentPosition = [touch locationInView:self.view]; 

CGFloat deltaX = fabsf(gestureStartPoint.x - currentPosition.x); 
CGFloat deltaY = fabsf(gestureStartPoint.y - currentPosition.y); 

if (deltaX >= kMinimumGestureLength && deltaY <= kMaximumVariance) { 
    //Set Animation Properties 
    [UIView beginAnimations:nil context:NULL]; 
    [UIView setAnimationDuration: 1]; 

    if(gestureStartPoint.x > currentPosition.x){ //I am trying to move right 

     ViewControllerTemplate *newView = [[ViewControllerTemplate alloc] initWithNibName:@"ViewControllerTemplate" bundle:nil]; 
     //Transition spin right 
     [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO]; 
     //Push OnTo NavigationController 
     [self.navigationController pushViewController:newView animated:YES];   
    } 
    else { //I am trying to move left 
     if([viewDelegate getCurrentViewID] > 0){ //At view 0, should not pop anymore view 
      //Transition Spin left 
      [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO]; 
      [self.navigationController popViewControllerAnimated:YES]; 
     } 
    } 
    [UIView commitAnimations]; 
} 
} 

差不多，它只是說，當用戶刷卡的權利，它創建一個新的視圖（ViewControllerTemplate）和pushViewController，當離開用戶刷卡，popViewController。但是，因爲我改變了主意，不想實現標籤欄。因此，我將appDlegate中的applicationDidFinishLaunching中的代碼更改爲下面的代碼，並在View1.m中的touchesMoved中的pushViewController停止工作。我確信它到達那裏，但是當它pushViewController的newView時，什麼都不會發生。我感覺當我拿出UINavigationController時，我的視圖不再適當地推入堆棧。任何想法，爲什麼，以及如何解決它

view1 = [[View1 alloc] init]; 
[window addSubview:View1.view];

一旦有人遇到同樣的問題，這裏是解決方案 更換什麼，我有在applicationDidFinishLaunching（）那裏本

view1 = [[View1 alloc] initWithNibName:@"View1" bundle:nil]; //Create the first view 
UINavigationController *navigationController1 = [[UINavigationController alloc] initWithRootViewController:view1]; 
navigationController1.navigationBar.tintColor =[UIColor blackColor]; 
view1 = navigationController1; 
[window addSubview:view1.view]; 
[window makeKeyAndVisible];
